angularjs - Difficulty adding multiple classes wit ng-class -

-

i'm trying add 2 classes div using ng-class, though checkforactive returning true, it's being ignored , class_{{$index}} getting added.

if remove class_{{$index}} altogether, active added correctly.

is there obvious mistake in syntax here?

<div "ng-class="{active: checkforactive, disabled: checkfordisable, class_{{$index}}} "></div>

you provide true value key class_{{$index}} property gets added class name class list of element. way active: checkforactive.

i.e

{active: checkforactive, disabled: checkfordisable, class_{{$index}} :true}

but believe there undesired behavior due usage of interpolation ({{) within ng-class directive (atleast used happen older versions). use array.

ng-class="[checkforactive && 'active' , checkfordisable && 'disabled', 'class_' + $index]"

the above method add class name false if active or disabled false, should harmless.

or pass index controller function getstatus($index) , return object there , use in ng-class directive.

 $scope.getclass = function(){      var obj = {active: $scope.checkforactive, disabled: $scope.checkfordisable};       obj['class_' + this.$index] = true;      return obj;  }

and

 ng-class="getclass()"

@okazari pointed out indeed works mixing class ng-class do:

class="class_{{$index}}" ng-class="{active: checkforactive, disabled: checkfordisable}"

c# - Where does the .ToList() go in LINQ query result -

when getting data populate data grid, have pulled data, made list , mapped model, this: public list<person> getpeople() { var data = _db.person.tolist(); list<person> people = new list<person>(); foreach (var item in data) { person person = new person() { personid = item.personid, firstname = item.firstname, lastname = item.lastname }; people.add(person); } return people; } this works fine, in interest of writing less code discovered .select method , (what think is) anonymous type. have: public list<person> getpeople() { return _db.person.select(d => new person { personid = item.personid, firstname = item.firstname, lastname = item.lastname }).tolist(); } though not easy read, works fine too. there preference either way? ...

Listeners to visualise results of load test in JMeter -

-
i want run load test in non-gui mode , save results in .csv file. (i have not modified .properties files, standard information saved) i plan load file , visualise results jmeter’s listeners. which listeners suited purpose? should avoid @ cost, might cause me misinterpret information? (e.g. in view results tree response data empty have - - not saved this. however, there has in fact been response. if saw listener might think there hasn’t been one. since want avoid this, listeners have gain information needed .csv file.) i’d know both jmeter listeners plugins. if running test in non-ui mode ideally should disable listeners in script. use '-l' option store test results .jtl extension. can later open jtl file jmeter. aggregate report or summary report should summarize test results , response time , throughput. if want plot graphs see trends on test duration can use http://jmeter-plugins.org/#/ standard , lib set. i suggest following listeners: response ...
